I am Ye Qing. Lucky I found a [Monster Factory] application.

Lu Liangwei wakes up to find herself transmigrated as a supporting character in the novel she had been reading a few days ago. According to the novel, this character has everything—beauty, wealth, status—except brains. Before Liangwei had taken over, she even went as far as to hang herself for the male protagonist that she loved: the Crown Prince as well as her sister's lover. Now that she has become a "brand new" person, it is time for her to turn her life around with charm and wit! She will get everyone to fall in love with her, even the Crown Prince's uncle—the Emperor! Who needs a prince when you can become the Empress herself?

When he woke up, Chen Xiao, a tech elite business genius, was reborn in a parallel world in 1999, another self standing at the gate of the college entrance examination.

OICQ was just born, and Goose Factory employees pretended to be girls and chatted with male netizens. Ma Yun was regarded as a liar and was forced to leave Yanjing to start a business in Suzhou and Hangzhou. Li Hong rented two rooms at the Yanjing Hotel and discussed the prototype of whiteness…

This year, Chen Xiao took the black technology guide of the future world, from social software to domestic systems, from domestic chips to artificial intelligence, from new biological energy to DNA remodeling to fight cancer; from quantum technology to anti-gravity engines…

He won the title of “Forbes” and dominated the global media. He suddenly found that he had accidentally changed the world.
